  • Energy efficiency communications over the AWGN relay channel 

    Gómez Vilardebó, Jesús; Pérez Neira, Ana Isabel; Nájar Martón, Montserrat (2010)
    Article
    Restricted access - publisher's policy
    This paper addresses the energy efficiency analysis of the relay channel under additive white Gaussian noise. We consider the rate bounds given by decode and forward and the cut set bound and assume that resources are ...

  • High-rate distributed multi-source cooperation using complex field coding 

    Cano, Alfonso; Gómez Vilardebó, Jesús; Pérez Neira, Ana Isabel; Giannakis, Georgios G. (2009)
    Conference report
    Open Access
    A multisource cooperative protocol is developed capable of achieving diversity order up to the number of cooperating users at a high throughput. In this design each source jointly encodes its own new information symbol ...
  • High-Throughput Multi-Source Cooperation via Complex-Field Network Codin 

    Li, Guobing; Cano, Alfonso; Gómez Vilardebó, Jesús; Giannakis, Georgios G.; Pérez Neira, Ana Isabel (2011-05)
    Article
    Restricted access - publisher's policy
    Physical-layer network coding over wireless networks can provide considerable throughput gains with respect to traditional cooperative relaying strategies at no loss of diversity gain. In this paper, a novel cooperation ...
  • MIMO channel modeling and transmission techniques for multi-satellite and hybrid satellite-terrestrial mobile networks 

    Pérez Neira, Ana Isabel; Ibars, C.; Serra, J; Del Coso, Aitor; Gómez Vilardebó, Jesús; Caus López, Marius; Liolis, K.P. (2011-06)
    Article
    Restricted access - publisher's policy
    The Quality of Service (QoS) in land mobile satellite (LMS) communications drops drastically in the presence of shadowing and multipath fading. This paper studies two promising multiple-input multiple-output (MIMO) schemes, ...
  • Statistical modeling of dual-polarized MIMO land mobile satellite channels 

    Liolis, K.P.; Gómez Vilardebó, Jesús; Casini, Enrico; Pérez Neira, Ana Isabel (2010-11)
    Article
    Open Access
    This Letter addresses the statistical modeling of dual-polarized MIMO-LMS fading channels. In the absence of accurate experimental results, a statistical model for the characterization of MIMO-LMS channels is proposed ...

  • Upper nound on outage capacity of orthogonal relay networks 

    Pérez Neira, Ana Isabel; Gómez Vilardebó, Jesús (2006)
    Conference report
    Open Access
    We consider the orthogonal multiple relay channel at the low SNR regime.The source transmits to the destination and all the possible relays in one channel and the relays transmit in different and orthogonal channels ...
